Technologies used:
Messaging Server
SpamAssassin
RBAC - execution profiles
Messaging Server use the two variables to hold the email accounts for feeding anti-spam system
with the positive and false positive spam messages:
- service.feedback.spam
- service.feedback.notspam
But there is no embedded mechanism to deal with them.
Here comes my solution.
Every time the Convergence user marks the spam (ot not spam), with the appropriate button from its interface,
the mail is being sent to the address provided within the configuration.
The email messages accumulate in the accounts and waiting for the action.
Scenario:
- fetching messages from spam account
- teaching spamassassin with spam
- cleaing INBOX folder
- fetching messages from notspam account
- teaching SA with ham
- cleaning account
Methods:
- fetching messages from spam account
- imsexport
- teaching spamassassin with spam
- sa-learn --spam
- cleaing INBOX folder
- mboxutil -d
- mboxutil -c
- fetching messages from notspam account
- imsexport
- teaching SA with ham
- sa-learn --ham
- cleaning account
- mboxutil -d
- mboxutil -c
Due to a fact the script will be invoked by root account, to get the access either to imsexport files or sa-learn with valid Bayes DB,
I have decided to use one of the Solaris RBAC mechanisms - profiles.
I would not describe the profile creation step-by-step, because the learning by example is much more valuable.

So, running sa-learn by the user / role with "SpamAssassin Administration" profile assigned
allow access to bayes DB files with the proper rights.
Examples can be seen in the script code provided below.

Run the script in a way you like.
I put it directly to a crontab. Root's crontab.
Enjoy.
